Drag and Drop Listeners Extension Points
Identifier:
org.eclipse.gmf.runtime.common.ui.services.dnd.dragDropListenerProviders
Description:
This extension point is used to register drag source and drop target listeners
against element types within view parts.This extension point facilitates
the configuration of providers for the drag/drop listener service (
org.eclipse.gmf.runtime.common.ui.services.dnd.core.DragDropListenerService).
The providers register listeners for drag and drop operations on specific element
types within view parts.
